Title: Incandescent image screen for cathode ray tubes
IPC: H01J29/16
Filed: 1937-03-02
Abstract: 479,318. Cathode-ray tubes. FARNSWORTH TELEVISION, Inc. March 2, 1937, No. 6182. Convention date, March 9, 1936. [Class 39 (i)] Incandescent image screens comprise separate parallel helices of fine refractory wire such as tungsten or tantalum mounted on a frame. The helices 6 are spot-welded to the frame 7 and supported by cross-wires 11. The helices, 250 per inch of the wires 11, may be scanned perpendicularly to their length and may each comprise 1200 turns per inch, the wire being finally etched to a diameter of À00025 inch. The screen may be heated to a dull-red glow independently of the scanning cathode-ray, for example, by direct or low-frequency alternating current, by infra-red rays or by an unmodulated electron stream. The scanning cathode-ray is focused electrostatically by an electrode extending along the wall of the tube from the anode to the screen or may be focused magnetically as described in Specification 467,366. Specifications 442,963 and 452,368 also are referred to.

Title: Improvements in and relating to rope gearing and the like
IPC: F16H7/04
Filed: 1929-02-26
Abstract: 329,708. Ohnesorge, O. Feb. 26, 1929. Driving-gear. - In rope, chain, and cable gearing for conveyers, hoisting and winding power, transmission etc., a rope etc., is wound more than once around a driving- drum upon an auxiliary endless chain, and means are provided for preventing axial movement of the points at which the rope etc., and chain wind on and off as the drum turns. For this purpose, the rope 16, Fig. 1 and 3, may be carried in leather, wood, etc., lined grooves of a chain of links 11 which may be driven by lugs 14<1> on the drum 10 and is guided by idler pulleys 12a, 12b. The links 11 are pressed axially, so as to maintain the positions of the links surrounding the drum by engagement with the curved or conical end x of the drum. The links are so pivoted together as to provide for easy flexure in all directions, and for adjustable spacing. The links may be pressed radially upon the drum by rollers upon stationary axes. The chain may comprise strips of fibre, leather, etc., forming part ot several links in series, additional metal plates being provided, if desired, to bridge the gaps between the links. Helical cams may be used to effect the axial chain movement and act through levers 38, Fig. 13, which are pivoted upon the pulley and engage stationary cams 40. Worms 30<1>, Fig. 16, may engage the links 11 and are rotated as the pulley 10 rotates, by gearing 59<1>, 60<1>, 34<1> engaging a stationary wheel 36. In a modification, teeth on the underside of the links are engaged by a spur wheel rotated by bevel gearing engaging a rotatable central wheel 36 which is geared by idlers on a stationary axis to a wheel on the shaft of the pulley.

Abstract: 1,118,074. Diaphragm pumps. N.R. ANDERSON. Feb. 10, 1967 [March 7, 1966], No. 6381/67. Heading F1A. A diaphragm pump for concrete and the like has a feed hopper 19 with an inlet 30 to the pumping chamber 27 which is covered by an outlet connection 34 during the discharge stroke. A crank and lever mechanism actuating the pump diaphragm 9 also acts to slide connection 34 between its positions covering and uncovering inlet 30, a pusher 68 and puller 69, Fig 4, transmitting the movement of diaphragm-actuating lever 72 to valve-actuating mechanism 56.

Title: Improvements in or relating to apparatus for use in the carbonisation and distillation of moist carbonaceous materials
IPC: C10B53/02
Filed: 1919-03-14
Abstract: 163,343. McLeod, H. N. March 14, 1919. Carbonizing apparatus. - Apparatus for carbonizing peat, sawdust, &c., in which the material is subjected to gradually increasing temperature in a succession of chambers, is provided with a number of separate heating-circuits. The material entering at the hopper 41 is passed successively through chambers 1, 2, 3, 4 by screw conveyers having hollow blades. The heating is primarily by a furnace or superheater 20 which supplies hot air through the hollow shaft extension 11 of the final chamber into the hollow blades 7 of the last conveyer and then through the connecting-piece 18 into the conveyer of chamber 3, and is returned to the superheater through a pipe 23, the jacket surrounding the extension chamber 12 and pipe 25. The carbonizing is effected in the strongly-heated final chamber, the more volatile hydrocarbons being led off to a condenser by a pipe 31 near the cooler end, and the gases released at the higher temperature obtaining near the end where the hot air enters are carried by pipes 32, 33, 34 to separate condensers. The cooling-fluid for the condensers is circulated by an exhauster 39 through the hollow blades 7 of the first two conveyers, entering at 37, passing through the connecting-piece 16 and leaving at 38, so as to give a progressive preliminary heating to the material as it passes through chambers 1, 2. The heating in the first chamber is supplemented by circulating through its surrounding jacket 42 the vapours given off in the intermediate chamber 3, pipes 41 being provided for this purpose. The heating in the second chamber is supplemented by passing gases from the furnace flues directly through the material under treatment from a pipe 27, these gases being withdrawn at the left-hand end by an exhauster 29. The pipes 31, 32, 33, 34 for carrying off the distillates may be jacketed with material having boiling-points approximating to that of the distillate required. The residue is discharged into a receptacle- 40 which may be a briquetting- machine.

Title: Improvements relating to control valves for fluid under pressure
IPC: F16K31/145
Filed: 1944-04-15
Abstract: 579,466. Pressure - regulating valves. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. April 15, 1944, No. 6983. Convention date, May 27, 1943. [Class 135] A pressure-regulating valve of the selflapping type comprises a pressure supply valve member 24 controlling the supply from a conduit 52 to a conduit 53 and a pressure release valve member 22 controlling the release of pressure past a stem 23 and through passages 36, 35 to atmosphere. The desired pressure in conduit 53 is obtained by a corresponding movement of a lever 43 which acts through a stem 32 on a comparatively strong spring 39 which moves a diaphragm 5, which carries a valve seat 20 for the release valve 22, downwards so as to close this release valve and open the supply valve 24. The pressure which builds up in conduit 53 and chamber 18 acts upon the diaphragm 5, through a restriction 51, to move it back to the neutral position in which both valves are closed and also acts through a passage 8 on another diaphragm 3 which is connected to the operating stem 32. The pressure on this latter diaphragm balances the upward thrust on spring 39 from the lower diaphragm and relieves the actuating lover 43 of strain. Any further movement of lever 43 in either direction causes operation of either of the valves 24 or 22 and a corresponding increase or reduction in the pressure in conduit 53. A friction device comprising a spring-pressed ring 46, Fig. 2, is provided on the spindle 44 of the lever 43 to prevent any unintentional movement of the lever by shock or jarring.

The crests of the corrugations are perforated by cutting knives 12, Fig. 8, or by punches, on rolls 11 co-operating with lugs 14 on an upper roll 15. Adhesive material, which may be asphalt or bitumen, pitches, sizes, or adhesive siliceous substances, is applied to the lower sheet 1 by immersion in a bath thereof.
